首先，我们研究了氯代乙酸存在下Pt／TiO_2上光催化生成氢的反应。

The fact that wastewater has higher chromaticity removal efficiency in acid medium than in basic medium indicates that H+ ions play an important role in chromaticity removal ,possibly by a mechanism of deoxidation in which H+ ionsreact with the organic compound of pollutants in wastewater and cause the chain rupture of chromophoric or anxochromic groups from the organic compound molecules.

事实已经废水色度去除效率高，比在酸性介质中显示基本氢离子色度去除起到了重要作用，可能的机制脱氧其中氢离子的反应有机化合物废水和污染物链条断裂造成anxochromic色或团体从有机化合物分子。

When the mixture of bacteria strain MH and fungi strain Cladosporium is used, the extent of diesel biodegradation is significantly increased by 80% after five days; Diesel pollutants in aqueous solution can be completely removed by synergistic use of these MH and Cladosporium; The observed synergistic effect is closely related to the aromatics-resistance of the fungi strain Cladosporium, which in turn favors the growth of the MH.

当分支杆菌菌株和枝孢属菌株混合使用时，柴油在五天后的生物降解率高达80%；通过分支杆菌菌株和枝孢属菌株的协同降解作用可完全除去水体中的柴油污染物；协同作用主要涉及到枝孢属菌株对芳香烃的降解而促进了分支杆菌菌株的生长。
